Helmetgate continues. Though the Oakland Raiders' mercurial wide receiver Antonio Brown found his Schutt AiR Advantage helmet made in 2014, which has been certified for use by the National Operating Committee on Standards for Athletic Equipment (NOCSAE), the NFL announced that the helmet failed.

Now, according to ESPN's Adam Schefter, Brown is still not at practice “because he's still upset with helmet issue.” Schefter notes that Raiders general manager Mike Mayock said,

“We need to know if he's all in or all out.”

Brown initially filed a grievance against the NFL for not allowing him to wear the Schutt Air Advantage helmet that was older than ten years old — against their policy. The receiver threatened to retire over the issue. Originally, after the NFL deemed his helmet (not the one made in 2014) unsafe, Brown released a statement on Twitter that said,

“While I disagree with the arbitrator’s decision, I’m working on getting back to full health and looking forward to rejoining my teammates on the field. I’m excited about this season appreciate all the concerns about my feet!”

It was reported earlier this week that Brown would be back on the field for training camp in preparation for the third preseason game. Now, that appears to be at risk.

Brown is also dealing with frostbitten feet, on top of the helmet issue. The seven-time Pro Bowler has played in just one training camp for the Raiders, over his helmet and what he calls “circumcised” feet. In culmination, Brown's case continues to be one worth tracking.
